There is no AMDGPU DC in 4.14.y, this was only added in 4.15.y. You can try a 4.15.0 LibreELEC build and see if that makes any difference. If you need a more recent mainline kernel to fix this issue then you'll need to look elsewhere as LibreELEC only ships LTS kernels now, which means 4.14.y for the next 12 months or so.

Thanks Milhouse. I will try that. From the talk in that other discussion, I may have to figure out a way to enable the DC for my SOC graphics.

So, I made a discovery last night. After trying several different LE9.0 builds, including #0129x version based on Linux 4.15.y (which supposedly adds AMDGPU DC). Still no luck. When I queried the modules (SSH>lsmod) it didn't show anything related to AMDGPU. After this, I was getting tired of messing around with the box and was ready to accept having Kodi convert the lossless audio to PCM multichannel.

So, I rolled it back to an official build (8.4.x?). I didn't spend to much time in the settings. To my amazement, it was all of a sudden passing DD+, DTS-HD MA and TrueHD!

What was the difference? It took me awhile of checking settings, and run some additional testing, but I finally realized that the difference is whether or not I select to have Kodi adjust the display rate to match the video (not sync display). If I have it set to adjust at start/stop, the lossless doesn't pass-through. If I turn off "adjust refresh rate" and let it stay at 60p, it will pass-through the lossless codecs.

I have ALWAYS had my Kodi boxes set to adjust the refresh rate at start/stop and it never prevented pass-through. So, there is something still not right with the drivers or Kodi. It should be able to pass lossless no matter what the frame rate. It should be EASIER for the box to send 24p. No reverse pulldown, no frame interpolation, etc.

This problem only seems to be an issue with this AMD GX-415GA SOC processor (eKabini, Radeon 8330e). I've used nearly identical settings on older (G-T48E) AMD APU chips, as well as with the Haswell Chromebox. Never an issue passing lossless.

Details I've been reading indicate that the Nuc platforms don't passthrough 'high quality' audio streams. Enabled Passthrough, enabled all the flags that my receiver supports, no audio when selecting DTS/DTS-MA audio tracks. Disabled Passthrough, and I get audio, and according to my receiver it's the x.1 DTS/DTS-MA audio stream, not just stereo. Not sure if this is just 'work in progress' and documentation hasn't caught up or if I missed something somewhere.

When scanning my movie collection the scraper misidentified a few things as I expected. I was able to correct them without much issue, but there are a number of movies in my collection that are older and instead of having spaces they have dots. For some reason the scanner refuses to let me attempt to correct the name like it does with other typo'ed or 'unconventional' names. It doesn't appear to try to parse the string at all, just errors out and gives up without presenting the ability to correct/change the name.

Other than the above, the Apr 2 build is running excellently on the platform.

Its stable.

It absolutely makes no sense that it gets slower after setting the minimal frequency to 750. Normal minimum is 200. 750 will just make sure it does not reduce the clock.

I understand that it makes no sense. At best setting the frequency did not help anything. The temperatures are almost the same and the framerate is the same-ish rubbish. I could post a video tomorrow if it would help anything but I doubt it will. Is it only my NUC6CAYH that is having these troubles with 10bit 4k video on the newest builds? @blokkie ??
